Drug & supplement interaction

Galacto-oligosaccharides (gos) + Sevoflurane

Sevoflurane brand name: Ultane.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Galacto-oligosaccharides (gos) and Sevoflurane in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Galacto-oligosaccharides (gos) and Sevoflurane

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Sevoflurane and Galacto-oligosaccharides (gos) in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Sevoflurane

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sevoflurane is filed under 2 classifications — anesthesia, oral drugs. Galacto-oligosaccharides (gos) has documented interactions with 1 drug class — the most serious being immunosuppressants (moderate) — and none of Sevoflurane’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Galacto-oligosaccharides (gos) and Sevoflurane May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • A severe allergic reaction Worth acting on Additional detail

    Galacto-oligosaccharides (gos)

    “Orally, GOS seem to be well tolerated in infants, children, and adults.

    Most Common Adverse Effects:

    Orally: Bloating, constipation, diarrhea, flatulence, and increased stool frequency.

    Serious Adverse Effects (Rare):

    Orally: Anaphylaxis in sensitive individuals.”

    Sevoflurane

    Listed in the ADVERSE REACTIONS section of the FDA label for Sevoflurane. Read the label on DailyMed ›

  • A skin rash Additional detail

    Galacto-oligosaccharides (gos)

    “Orally, giving a formula supplemented with 4 grams/L of GOS and polydextrose (1:1 ratio) to infants has been associated with an increased incidence of atopic dermatitis in one clinical study. However, most other clinical research in infants at risk of atopy shows that GOS-containing formula may actually reduce the risk of developing atopic dermatitis.”

    Sevoflurane

    Listed in the ADVERSE REACTIONS section of the FDA label for Sevoflurane. Read the label on DailyMed ›

Reported for Galacto-oligosaccharides (gos) but not commonly for Sevoflurane: constipation, bloating or gas and diarrhea.

Effects for Sevoflurane come from the ADVERSE REACTIONS section of its FDA label; effects for Galacto-oligosaccharides (gos) come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,843 voluntary FDA FAERS reports for Sevoflurane that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Everything else you take

See Every Supplement That Interacts With Sevoflurane

This page covers Galacto-oligosaccharides (gos) only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sevoflurane page lists 22 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Fever Bark (major), Cannabis (moderate), Coffee Charcoal (moderate) and Cowhage (moderate).

By severity: 2 major · 11 moderate · 9 minor.

From our pharmacist’s overview on the Sevoflurane page

“Fever bark is the supplement I would want disclosed first before anyone receives sevoflurane (Ultane), the inhaled anesthetic used during surgery. Its reserpine content has been tied to unstable heart function and circulation under general anesthesia, earning one of two major ratings among the 22 ingredients on this page.”

About Galacto-oligosaccharides (gos)

What is Galacto-oligosaccharides (gos)?

  • Prebiotic to support gut bacteria
  • Constipation
  • Digestive health
  • Immune support
  • Infant gut health

Galacto-oligosaccharides (GOS) are a type of prebiotic fiber that feed the helpful bacteria in your gut. They are generally well tolerated and may help with digestive regularity and gut balance, though they can cause gas and bloating, especially at higher doses. Evidence is promising but still limited for many uses, so talk with your pharmacist or doctor before starting.

Carbohydrate derived from lactose (milk sugar) · Powder, capsules, chewable tablets, added to foods, infant formula, and functional drinks

Galacto-oligosaccharides (gos): dosing

There is no single official or standardized dose for GOS. Studies have used a range of amounts, and the right dose can vary from person to person.A common, practical approach is to start with a small amount and slowly increase it over days or weeks.

Taking Galacto-oligosaccharides (gos) and Sevoflurane Together: Common Questions

Is it safe to take Galacto-oligosaccharides (gos) with Sevoflurane?
We do not list a known interaction between Galacto-oligosaccharides (gos) and Sevoflurane. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Galacto-oligosaccharides (gos) and Sevoflurane have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Galacto-oligosaccharides (gos) and Sevoflurane combination checked?
Interactions in our licensed database are recorded against drug classes. Sevoflurane is filed under 2 classifications, and Galacto-oligosaccharides (gos) has documented interactions with 1 drug class — none of Sevoflurane's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Galacto-oligosaccharides (gos) interact with any other medications?
Yes. Galacto-oligosaccharides (gos) has 121 documented drug interactions in our database — Sevoflurane is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Sevoflurane interact with any supplements?
Yes. Sevoflurane has documented interactions with 22 supplements in our database — Galacto-oligosaccharides (gos) is not one of them. The Sevoflurane interaction page linked on this page lists every one, ranked by severity.
